GT-i9000 2.2 Froyo software, need help with Home button...

So my buddy David is a developer and has almost got Froyo 2.2 on the Vibrant with the GT-i900 software but has a problem with the Home button. The button is currently only acting as a back/return function. Quick Launch isn't working and it doesn't bring up the homescreens preview. Can anyone that knows ODIN help with getting the home button functioning again?
